To all whom it may concern: .ie it known that I, HENRY HARRINGTON, oflVaukegan, in the county of Lake and in the Stateof Illinois, haveinvented a certainnew and useful Improvement in Portable ConveyingApparatus; and dohereby declare that the following is a full, clear,'and

' kinds and in which the elevator, furthermore, may be readily used notonly to con-- vey materials up to the pile, but to convey the piled upmaterials downwardly away from the pile, and to convey'materials from ione point to another.

lVhile my lnvention' is capable of embodiment in many different forms,for the purpose of illustration I have shown only one form thereof inthe accompanying drawings, in which- Figures 1 and l show a sideelevation of an apparatus made in accordance with my invention;

Fig. 2 is an enlarged detail of the same showing a front elevation; and,

Fig. 3 is a side view of a detail of the elevator mechanism, said detailbeing the part shown in Fig. 2.

In the drawings I have shown a truck 1 of any desired construction,mountedupon wheels 2. Said. truck 1 has a supporting frame comprised ofvertical beams 3, inclined beams 4, and horizontal beams 5. The verticalbeams 3 support, in suitable bearings, a horizontal shaft 6 carrying apulley 7, said pulley being driven by a belt 8 from a pulley 9 on ashaft 10,,carr1ed by the truck 1, and being driven from any suit ablesource of power by a pulley 11. The

shaft 6, furthermore, carries a sprocket 12 which is connected by achain '13 to a sprocket 14: on a shaft 15 located on the horizontalbeams '5. This chain 13, however, passes over an idler roll 16 supportedin the vertical beams 3 in order to maintain the same taut. The shaft15, furthermore, has a sprocket 17 which is connected by a chain 18 to asprocket 19 on a shaft 20, which is supported in arms 21 forming poritions ofsectors pivotally carried by the shaft 15 and loosely supportedthereon. Said sectors 22 have gear teeth 23 which mesh with gears 24located on a shaft also supported by the vertical beams 3, said shaft 25being adjustable manually by means of a hand lever 26 having an auxibiary lever 27 for operating, by means of a spring-pressed rod 28, acatch 29 for engagmg teeth 30 on a ratchet wheel 31 tightly secured tothe shaft 25. A further catch 32 is pivoted to a bracket 33] on thevertical upright 3, said catch 32 being provided to engage with theteeth 30 to maintain the shaft 25 in any desired adjusted position.Pivoted to the shaft 20 there is a lower eonveyer arm 3d which issupported by rollers 35 on the ground at the other end thereof, andwhich has at the lower end, ustable bear ings 36 for supporting a roll37, over which a convcyer band 38 passes, said conveyor band 38 beingcarried at its other end. upon a roll 39 tightly secured to the shaftUpon the shaft 15, furthermore, there is an upper conveyer arm 40 whichhas at its outer end adjustable bearings 41 for a roll 42 which carriesa conveyor band 43, the other end of which passes around a pulley 44secured to the shaft The' outer end of the upper conveyor arm 40, issupported upon a roll 45 which is located upon'the end of a link 46pivoted at its lower end to the .r

truci; 1, said link 4L6 having its. outer and held in any desired.position by a red 4C7;

having a turn-buckle 4.8 which is connected to a pulley 4-9 carrying acable one end which is fixedly secured ton book 51 sup ported upon oneof thehorizontal beams 5, while the other end thereof passes over a drum52 having a gear 53meshing with-agear 54 on a shaft 55 adapted to berotated by a hand crank 56.

applied to the conveyor bands 38 and 2:3 by any suitable source of powerapplied to the driving pulley 11. I 40 is adjusted to the height of thepile of material by rotating the hand crank so as to wind up or unwindthe cable 50 upon the drum 52. The movement of the cable 50in thismanner elevates or lowers the link 46 and elevates or lowers therewiththe up- In the operation of my invention, power is Theupper c'onve'yerarm 7 conveyer arm 34 is located in the position shown in Fig. 1. If.however, the material is to be conveyed dmvnwardly, away from the pile,the catch 3:2 is released and the 5 hand crank 26 is operated so as toallow the shaft to rotate a distance sufficient to lower the upper endof the conveyor arm- 343 to a point below thelevel of the upperconveyer' arm it). The catch 52 is then again 0 applied to the teeth 30to retain the lower con'veyer arm 8t in its adjusted position. Materialsbeing conveyed downwardly from the pile as, for example, in bags, maynow readily pass downwardly along the upper 5 conveyer arm l0. andfinally down the lower conveyer arm 3i until they have reached It is tobe understood however that my in-- vention is applicableto any beltconveyor system where the direction of movement of 30 the materials isto be reversed;

While I have described my invention above in detail, I wish it to beunderstood that many changes may be made therein without departing fromthe spirit of my invention.

I claim: 1.. In combination, a first oonveyer arm, a second conveyer armand means for ad justing the relative elevations of the adja- 40 centends of the conveyer arms, comprising a link connecting said two ends,and a sector fixed to the link, and a gear for moving the sector. 2. Incombination, a first conveyer arm, a second conveyer arm and means foradi justing the relative elevations of" the adjacent ends of theconveyer arms, comprising a link connecting said two ends, a sectorfixed to the link, a gear for moving the sector and a toothed wheel andcatch for maintaining the adjustment of the parts. I 3': A eonveverhaving a section of fixed elevation; an adjacent arm having its free endprovided with a supporting means permitting lateral movement ot saidend, and a connection between the adjacent ends of said section and arm,and means to move adjacent end of the arm.

4. A conveyer having a section of fixed elevation, an adjacent conveyerarm, a link pivoted to the adjacent ends of said section and arm, andmeans connected to said link to produce angular movement of the latterto vary the relative elevation of said adjacent ends. I

5. In combination, a pair of adjacent conveyer arms, a link pivoted toan end of one arm, a shaft supported by said link and ournaled in theadjacent end of the other arm, and means for rotating said link to varythe relative elevation of said adjacent ends.

6. In combination, a pair of adjacent conveyer sections, connectionbetween the adjacent ends of said sections, and means to said connectionto vary the elevation of the move said connection to vary the relativeelevation of said adjacent ends.

7. In combination, a pair of adjacent conveyer sections, a linkconnecting the adjacent ends of said sections, and means for moving saidlink to vary the relative elevation of the adjacent ends of saidsections while maintaining substantially a constant elevation of. theremote ends of said sections.

8. In combination, a pair of adjacent conveyer sections, links pivotedto the adjacent ends of said sections, and means to impart angularmovement to said links about one of said pivots to vary the relativeelevation of the adjacentends of said sections while maintainingsubstantially a constant elevation of the remotends of said sections.

9. A conveyerhaving a section of fixed elevation, an adjacent movablesection, links pivoted to the adjacent ends of said sections, and meansto impart angular movement to saiddinks about the. pivot of said fixedsection to vary the elevation of the adjacent ends of themov-ablesection while maintaining substantially a constant elevation ofthe remote ends of said sections.

- 10. A conveyer having a section of fixed elevation, an adjacentsection having a roller support at its free end, and a connectionbetween the adjacent ends of said sections, and means to move saidconnection to vary the relative elevation thereof.

in testimony that I claim the foregoing I have hereunto set my hand.
